Deferred Rendering Techniques

on Mobile Devices

Ashley Vaughan Smith

2.1 Introduction

With ongoing advances in GPU technology and the introduction of OpenGL

ES 3.0, it has now become possible to utilize rendering techniques that were

previously only usable on desktop GPUs. Applications that use dynamic lighting

require a technique to shade the scene in an efficient way in real time. On mobile

devices with a low power requirement, this is difficult to achieve.

This chapter discusses the available techniques for deferred rendering [Harg-

reaves and Harris 04] on mobile devices and implementation details that allow

optimized rendering of these techniques. ...
